Per this thread where you helped us: BCM53125 jumbo frames
We were able to program 53125 using the SPI interface for "Jumbo Frames". Everything seems to work well until we power down the chip. At power up the register changes are lost. How can we save the registers to keep the values over power cycle?
1. If there is an external CPU on your platform, your CPU software should be able to program the "Jumbo Frames" feature setting via SPI after power on of power cycle.
2. If your platform is unmanged without external CPU,

2. If your platform is unmanged without external CPU, it can store the "Jumbo Frames" feature setting registers write into external EEPROM device, and 53125 will to load EEPROM device setting after power on of power cycle.
